Information on Cardiovascular Disease in the Digital Era: Results From a Cross-Sectional Patient Survey.

Public health strategies to reduce cardiovascular disease (CVD) rely on the effective dissemination of evidence-based information to at-risk populations. An improved understanding of the information sources patients use can facilitate content development and promote awareness of effective interventions for CVD prevention, monitoring, and management. We therefore sought to determine the contemporary patterns of CVD information source usage via a prospective, cross-sectional survey study of CVD information sources in a primary care centre in Ontario, Canada. Primary source(s) used for CVD information were defined as: traditional media (television or print media), Internet-based sources, or community resources (community agencies and health care providers). Of 4682 consecutively screened patients aged > 18 years 3189 (68%) participated in the survey. The mean age of the survey respondents was 37 ± 14 years and 54.4% were female. Traditional media (71%) were used more frequently than Internet-based sources (45%) or community health services (23%). Only 20% of respondents identified health care providers as the source of information for CVD. Compared with respondents aged ≥ 55 years, the adjusted odds of Internet-based source use were significantly higher among younger age groups, whereas the adjusted odds of print media and health services usage was lowest among ages 25-34 years. Although traditional print and electronic media remain the primary resource for CVD-related information, younger individuals increasingly rely on Internet-based sources. These findings have important implications for public health policy and resource allocation, highlighting the importance of maintaining traditional media presence in addition to the development of high-quality Internet-based sources of CVD information.
